So, I decided to put this out there on the off chance that it might help at least some people out. I'd been having issues with getting some songs to work/load in RS. Whenever I loaded in, some of my customs would be there, but others wouldn't. I tried reinstalling, reconverting, anything to try to figure it out or get them to work. Nothing. Several were by the same uploader, band, etc, just different songs. Then this happened by accident. I was messing around with the song list for the umpteenth time, and started to exit out. I got to the main title screen again, and then changed my mind about quitting, wanting to test another setting. When I went back into my song library, holy heck, all of them were there! I spent several minutes testing variables, messing with other menu settings, just waiting to see if the songs would load, etc. But the only consistent thing I found was loading in, exiting to the main title screen, and loading back in. Every time. So, tldr: If you can't seem to get your CDLC songs to appear, try exiting to the main title screen and then loading back in again. I have no clue why this works when nothing else did, but hey, I have my songs so I don't care!
